A hidden AirTag in your bag. A GPS tracker under your car. An ex who always knows where you are. SentryRF uses on-device AI to detect hidden trackers, planted devices, and people following you — even if they're using a phone, not a tracker. The AI learns what's normal and alerts you to what isn't. 100% private. No accounts. No cloud. No one knows you're scanning.
These situations are more common than people think. SentryRF helps you find the truth.
An ex, a stalker, or a stranger slipped a small tracker into your purse, jacket pocket, or car seat. It silently reports your location through Apple's Find My network — no pairing, no notification, no visible sign.
A magnetic box under the wheel well, inside the bumper, or behind a panel. Your ex, a stalker, or a PI now sees every trip you make — your therapist, your lawyer, your new apartment.
No tracker needed. A person following you on foot or by car — their phone's Bluetooth is an unintentional beacon. You feel watched but can't prove it. Most tracker apps would show nothing.
A device you don't recognize appearing outside your home repeatedly — during the day, at night, across multiple days. Someone casing your location or watching your routine.
A Tile, SmartTag, or AirTag concealed inside a stuffed animal, a book, electronics, or a piece of jewelry. Given as a "gift" but designed to track your every move.
A tiny camera behind a mirror, inside a smoke detector, or in a USB charger. An audio recorder hidden in a room. Planted by someone with access to your space — a partner, a landlord, a roommate.
Someone across the table wearing Ray-Ban Meta or Snap Spectacles — recording your conversation, your face, your location without your knowledge or consent.
You've found a tracker. You've detected a follower. You need documentation for a restraining order, a police report, or a lawyer.
